N-Methyl-L-Tryptophan has been isolated from the seeds of Abrus precatorius, a plant native to Taiwan [300]. Sarcosine (N-methylglycine) is more widely distributed and has been detected in various animal and plant Tissues [301–303] (p. 329). Furthermore, there is Evidence for the presence of N-methyl derivatives of Isoleucine, Leucine, and Valine within The Structure of enniatin group Antibiotics [304]. 1-Methylhistidine is a constituent of anserine and has been found in a free state in urine and Kidney tissue [305–307]

3-Methyl-L-Histidine was isolated from human urine using Column Chromatography [308]. In its properties, the isolated product is identical to The amino acid obtained via chemical synthesis.

Natural N-methyl Amino Acid Derivatives also include N-methyltyrosine (surinamine) and stachydrine (p. 349).
